A spherical portion 8 that bulges to the side) is formed in the inside, and a contact edge 9 is bent and formed around this spherical portion 8 in an inclined state toward the indoor side. The spherical portion 8 is provided in order to efficiently receive the differential pressure between the indoor and outdoor areas, which will be described later.
このダンパ翼３は、球面状部８の中心に形成した軸受け
部１１に摺接・挿通する軸部材１２にて支持されつつ矢
示Ｂの如く進退動するようになっているもので、圧縮バ
ネ１３により建物室外側（閉方向）に付勢されている。The damper blade 3 is adapted to move forward and backward as shown by an arrow B while being supported by a shaft member 12 which is slidably contacted with and inserted into a bearing portion 11 formed in the center of a spherical portion 8. It is urged by 13 toward the outside of the building (close direction).
